fts: Initialize fts after namespaces have been added

This way paths are correctly set, and fts indexes are
written to correct place. This affects mbox with lucene.

Fixes Panic: file mailbox-list.c: line 1158 (mailbox_list_try_mkdir_root): assertion failed (strncmp(root_dir, path, strlen(root_dir)) == 0)
