Only show Mail Merge toolbar after wizard finished

The toolbar is not needed while wizard works (since it's modal).
This simplifies the logic a little.

Also this allows to show the toolbar in the actual document used for
mailmerge (e.g., when a new or existing document is used, nit the
current one); previously, the toolbar appeared in the document active at
the moment of wizard launch remained in that document, and actual
document went without the toolbar.
