commands/account: Disable :view for deleted msgs

Allowing the user to view deleted messages creates all sorts of race
conditions. The most devious race condition is pv.source can be set to a
nil while another PartViewer is still running a goroutine in

Here is a trace when this happens.

goroutine 76 [running]: io.copyBuffer(0x7f8ad02641d0, 0xc00040f590, 0x0,
0x0, 0xc0007cc000, 0x8000, 0x8000, 0x0, 0x0, 0x8b3d60)
/usr/lib/go/src/io/io.go:402 +0x101 io.Copy(...)
0xc0004da7c0) /home/keur/repos/aerc/widgets/msgviewer.go:576 +0x611
created by git.sr.ht/~sircmpwn/aerc/widgets.(*PartViewer).attemptCopy
/home/keur/repos/aerc/widgets/msgviewer.go:544 +0x144

We could add a guard in store.FetchBodyPart to only call the callback
when msg.Part.Reader != nil, but we still get a hanging pager. Therefore
it seems more reasonable to disable this completely.

Tab completion currently only works on commands. Contextual completion
will be added in the future.
