Fix unit test in IE7

[vojtajina]

This commit fixes 2 tests in IE7, so now all tests pass in IE7, IE8 on my machine.

Unfortunately there is still one test, that is even not executed in IE - there are 810 tests executed in Chrome / FF / Opera, but only 809 tests in IE7 / IE8.
That's problem of JSTD, it silently ignore tests with syntax errors:

Just for future info, the one test which is not executed on IE is not an issue, as there is a condition to run the test only if not IE browser:
