Follow up of commit a3845ae3f0
Issue
=====
Since the above commit there is a confirmation dialog when clicking on a button,
for which the only options are to Discard or Cancel.
The problem is that when discarding it will revert the selected website back to
the default value. Therefore before the current commit it is impossible to
install a theme on a website other than the first.
Solution
========
The solution is to avoid showing this dialog when clicking on buttons for which
the result depends on the currently selected website. This leads to the same
behavior as what existed before the mentioned commit: the settings are
implicitly discarded because they are not saved, but at the time of the click
the transient model still holds the non-discarded value that the user selected.
This restores the "select a theme" feature, but also restores the unfortunate
side effect that the user might unknowingly loose all of his pending changes
when clicking on the button, but only for those two specific buttons.
Other considerations
====================
Saving instead of Discarding was considered but it is impossible to do because
saving might do a lot of changes that might even lead to the installation of
modules, so the settings page has to be reloaded to apply them, and then the
website field will be reset to its default value again.
Instead of changing website specific settings from the main settings, it was
considered to update them through a form view, but it is apparently too
complicated for on-boarding.
The last consideration was that the settings view should actually mark the
corresponding fields as unchanged when changing the website, but it is too
complex to implement for a case that is not supported in the first place,
especially for a fix in a stable version.
