remove EPS bearer deletion when going RRC idle 

when going RRC idle, NAS gets informed and currently
clears all registered EPS bearers. This is wrong because
the EPS can outlive a RRC session.

Also in the conformance tests it's clearly seen
that after a RRC release a dedicatated EPS bearer is
created with a linked EPS bearer ID that has been
created _before_ RRC went idle.
