Some typos in pattern tests

[chloestefantsova]

Here are some more places in the tests that seem to need small corrections.

---

co19/LanguageFeatures/Patterns/map_A04_t02.dart

Lines 91 to 92 in 4b14012

	var {c1: a1, c2: b1} = {c1: 1, c2: 2};
	Expect.equals(2, a1);

Here the variable is initialized to 1, but its value is checked against 2.

co19/LanguageFeatures/Patterns/variable_A02_t01.dart

Lines 112 to 113 in 4b14012

	case {2: final b}:
	b.substring(0);

co19/LanguageFeatures/Patterns/variable_A02_t01.dart

Line 214 in 4b14012

Expect.equals("{2: true}", testMap1({2: true}));

Here a boolean variable is captured by a variable pattern in a variable of type dynamic, and then the .substring method is invoked on it, resulting in a runtime error.

co19/LanguageFeatures/Patterns/variable_A02_t03.dart

Line 56 in 4b14012

return "(<int>$g, final $h)";

co19/LanguageFeatures/Patterns/variable_A02_t03.dart

Line 103 in 4b14012

Expect.equals("(<int>0, final false)", test1((0, false)));

Here it seems just an extra space was added in line 56 before the word final.

co19/LanguageFeatures/Patterns/variable_A02_t04.dart

Line 53 in 4b14012

return "[<String>$e, <bool>$f]";

co19/LanguageFeatures/Patterns/variable_A02_t04.dart

Line 102 in 4b14012

Expect.equals("(<String>y, <bool>false)", test1(["y", false]));

Here it seems that parentheses in line 102 should be replaced with square brackets.
