fix issue when unit starts with dot

Fix for the bug #402

[dcslagel]

Draft branch at #413, demonstrates test cases for additional [name][.][unit] parsing scenarios.

The tests make assumptions about the desired behavior that should be checked. Three of the tests currently fail. This could be because the test is incorrect or because additional code changes are needed to fix the test scenario.

Hi @eimerej , @kinverarity1 ,

After spending a fair amount of time looking that this, @eimerej 's solution in pull-request #403 is the right one for now. It takes care of the cases .1 and .2 that I listed in issue #402 and the cases .3 and .4 are highly unlikely and can be solved if there is ever a real-world case reported. Case .5, @kinverarity1 , mentioned it is okay to let it resolve with the current logic in Laisio.

So all that said, I encourage merging pull request #403. Thank you for allowing me to dig in to this problem for an extended period of time.
