New file creation takes a really long time

[elzody]

Describe the bug
When creating a new file on a fresh NC30, it takes a really long time when creating a file for the template picker to appear. When the richdocuments app is disabled, this issue does not occur. It is probably something to do with templating, or Collabora trying to get some additional file information.

To Reproduce
Steps to reproduce the behavior:

1. Have a fresh NC30 or private browser window with no cache
2. Try to create a new text file

Expected behavior
It is expected that new file creation happens quickly and that the template picker does not take so long to appear.
