Fix bug:about the MVC package route binding

[BenLampson]

I found there has some little bug in the controller_method_parser.go
the bug is: if someone uses the code like this:
func (cc *HelloWorld) GetInfoXYT()
We can't create the Url that he wants.
We lost the T, our URL is: info/x/y
Cause I found the comment in this scope,
Like this:// it doesn't count the last uppercase
And I think the author tries to append the lastest Code, but the last append is
words = append(words, s[start:end])
You know, If the string is GetInfoXYT the end index is the same as the start, so we lost the T.
I think this processing mode can not be accepted, so I try to fix this.

We'd love to see more contributions

Hello @BenLampson,

Did you find out that this is the solution to your problem? And also could you please add a test case at:

iris/mvc/controller_test.go

Lines 385 to 412 in df88227

	type testControllerRelPathFromFunc struct{}
	func (c *testControllerRelPathFromFunc) BeginRequest(ctx context.Context) {}
	func (c *testControllerRelPathFromFunc) EndRequest(ctx context.Context) {
	ctx.Writef("%s:%s", ctx.Method(), ctx.Path())
	}
	func (c *testControllerRelPathFromFunc) Get() {}
	func (c *testControllerRelPathFromFunc) GetBy(uint64) {}
	func (c *testControllerRelPathFromFunc) GetUint8RatioBy(uint8) {}
	func (c *testControllerRelPathFromFunc) GetInt64RatioBy(int64) {}
	func (c *testControllerRelPathFromFunc) GetAnythingByWildcard(string) {}
	func (c *testControllerRelPathFromFunc) GetLogin() {}
	func (c *testControllerRelPathFromFunc) PostLogin() {}
	func (c *testControllerRelPathFromFunc) GetAdminLogin() {}
	func (c *testControllerRelPathFromFunc) PutSomethingIntoThis() {}
	func (c *testControllerRelPathFromFunc) GetSomethingBy(bool) {}
	func (c *testControllerRelPathFromFunc) GetSomethingByBy(string, int) {}
	func (c *testControllerRelPathFromFunc) GetSomethingNewBy(string, int) {} // two input arguments, one By which is the latest word.
	func (c *testControllerRelPathFromFunc) GetSomethingByElseThisBy(bool, int) {} // two input arguments
	func TestControllerRelPathFromFunc(t *testing.T) {

in this PR so I can accept it?

Thanks!

Yeah~ In my project we have a Url resource to get the item's location, so our URL is: GET:api/v1/xxx/item/{int}/location/x

And my project already accepted this solution.

OK @BenLampson ,

I've pushed a commit to your PR as well, just to know whenever you add a test controller method you should fire the requests as well:

	e.GET("/location/x").Expect().Status(iris.StatusOK).
		Body().Equal("GET:/location/x")
	e.GET("/location/x/y").Expect().Status(iris.StatusOK).
		Body().Equal("GET:/location/x/y")
	e.GET("/location/z/42").Expect().Status(iris.StatusOK).
		Body().Equal("GET:/location/z/42")

Thx for your tips~ I learn the more things from your proposal~
I will add the more things in my other commit next time~
