Commit 3a614e45fc ("threading: enable toggle-threads for server-side
threads") changed the behavior of the msgstore.buildThreads variable to
reflect whether the client needs to build threads or the server will.
However, a call to runThreadbuilder was not updated with an extra
conditional. As a result, threads were built regardless of the state of
the threadedView resulting in a large performance penalty for
non-threaded views with client side threading.
Only run thread builder if threaded view is enabled.
