Refactored kTestString occurences in bridged_native_widget_unittest.mm

As per the CPP style guide, variables declared constexpr or const, and whose
value is fixed for the duration of the program, are named with a leading "k"
followed by mixed case. Since objects don't have a constant value for the
duration of the program, refactor "kTestString" to "test_string".
