[Dovecot] fts-solr indexer-worker connects to wrong solr host dovecot-2.2.4

[Richard Platel]

Hello.  
We're setting up fts solr and want to have the solr server host be set per-user via UserDB.

It looks like if a user connects and fts indexes mail, and then another user connects and indexes mail, indexer-worker is connecting to the first user's fts host:

User1, hammer at rp-auth-test.com connects, does a SEARCH for the first time, indexer-worker gets UserDB settings and correctly indexes mail on ftsvs01:
