fix: Fix for failing test in NSString+Utilities 

The test in TestNSString+Utilities would otherwise fail:

======================================================================
FAIL: test_countOccurrencesOfString (TestNSString+Utilities.m:46)
----------------------------------------------------------------------
assertion failure

Simply leave the loop early if the substring length is zero to
avoid this issue
