bug#4981: C-l during query-replace

I fixed `gnus-recenter' in gnus-sum.el.

Installed.  Currently I have no opinion about renaming
`recenter-top-bottom' to something more reasonable.

I can't find a clean solution because in the case of query-replace,
`this-command' is always `query-replace'.

This patch kinda works (though it doesn't reset the cycling order),
but I don't like this.
