fix(messaging, android): properly shrink stored messages to limit

previously, stored messages were cleared one at a time each time a message
came in, opening the possibility that the store would contain more messages
then the limit and never get back down to the limit.

now it will attempt to shrink down to the limit every time a message comes in
ensuring that if there is an over limit condition it will be fixed quickly
