[TYPO3-core] RFC # 15029: Testcase for t3lib_div::isFirstPartOfStr is missing.

[Steffen Kamper]

Hi Nikolas,

cool - that's really fast cooperation!

Just from reading, could you add some more cases to the dataprovider? 
Still missing some other wrong combination like
array/string
string/array
string/NULL
hello/bye

So we have all possible wrong param usages in the test.
Other than that test looks fine!
