[REVIEW 4.0] Template manager fixes

[Cedric Bosdonnat]

Hi all,

I have some patches fixes various tiny bugs in the new template manager
pending review for integration in 4.0. Could someone review them?

I first tried to push them to gerrit:
  https://gerrit.libreoffice.org/1610
  https://gerrit.libreoffice.org/1611

And then some more arrived, and I will simply list them here:
  Removing the "All" tab page as requested by UX people

Thanks for your reviews.
