Dirk-Jan C. Binnema d2343c6d62 mu-server: try avoiding xapian multi-threaded access 
Try to avoid multi-threaded operations with Xapian.

This remove the thread workers during indexing, and avoids the indexing
background thread. So, mu4e has to wait once again during indexing.

We can improve upon that, but first we need to know if it avoids the
problem of issue #2756.
