To speed up pull request flow, put e2e tests
only mandatory for Chrome.
We still have tests for Firefox and Webkit,
but they are not mandatory.
They will still have to be checked regularly,
particularly during the deployment phase.
If a user wanted to access a doc but was not logged in,
they would be redirected to the login page.
After logging in, they would be redirected to the home page.
This change makes it so that they are
redirected to the doc they originally wanted to access.
Usefull from the mail sent to the user to access the doc
they were invited to.
The tests e2e need the mail template to
send the invitation to the user.
We are now caching the mail template instead
of using a artifact, thanks to that we can
build only the mail template if the cache is
invalidated, so we save time and resources.
Add a test to check the pdf export of the
impress app.
It intercept the download of the PDF and
read its content.
We can assert that the template is correctly
rendered, and that the pad text is present as
well.
