[PATCH] Remove uneccessary strncmp call in imap-send count_messages

[Andy Parkins <andyparkins@gmail.com>]

The strncmp() call in count_messages() was doing the same comparison that 
strstr() did, so there was no need to call it.  A little rewrite and 
count_messages() is simpler.

Obviously no huge benefit, as it's not frequently called.  I'm just getting 
familiar with git.
