Neill Magill 22481f3d89 MDL-59317 message: Message page taking long time to load ...

The OR clause in these queries used different sets of columns to select
userid which meant that the indexes that included user id could not be
used.

This change splits the query so that each individual part can use one of
the indexes that includes a userid which speeds them up considerably.
