Fix crash occuring when using Recognizer

The SR_RecognizerResultGetKeyList should return [Ljava/lang/String,
however the code as written before the change will actually return
[[Ljava/lang/String

This "worked" before, probably by accident, but since
dvmFindArrayClassForElement has been rewritten to no longer used a
cached arrayClass. The dvmFindArrayClassForElement actually prepends
the [ and it should not be in SR_RecognizerResultGetKeyList.
