Address ignored tests in ComboBoxTest, LabeledTest, HyperLinkTest and TextInputControlTest.

strategy is as follows -

1) Enable tests marked with @Ignore by removing that tag
2) Run the test
3) If test Passes - remove the @Ignore tag
4) If test fails - if test is invalid - remove it, else fix the test
5) In case if the failure cannot be fixed, leave the test ignored (keep @Ignore tag)
