msgstore: check if message index < 0, select 0 if so 

Calling :prev without this check can cause the index to go below 0 if
the current index is smaller than the value being scrolled / incremented
by. This results in the email selector wrapping around from the top to
the bottom most email in the mailbox folder due to changes in ec150f0
'store: fix Select behaviour'.
