Don't get Gtp->Activity statements twice
Don't get Gtp->Activity statements twice

Previously the query was picking up Activity-->GtpBound statements
twice, once in the ActivityActivity query and again in the RasGef/RasGap
query.

These queries could probably be combined into one and then the correct
statement would be constructed based on the activity type field for the
object.
