Subject: Backport revision 1137928 from trunk

    Fix server crash associated with the replicator database

    If there's an exception when calculating the replication ID
    for a replication document, it crashes the replication manager
    gen_server 10 times. 10 is the maximum number of restarts per
    hour specified for the couch_server_sup supervisor.
    An easy way to trigger such exception is to specify a non
    existent filter in a replication document.

    This closes COUCHDB-1199.
