fix accidental overwriting of variable in bulkmailer #3862

When the bulkmailer tries to skip own or minor edits, it was overwriting
$rev with a timestamp instead of using the proper array structure
returned by getRevisionInfo().

This also moves the initialization of the PageChangeLog object out of
the while loop to ensure it's inner caching mechanism is utilized when
fetching the info.

This should fix #3862

Fix warning from toolbar.php when $INFO is null

This commit fixes an issue observed in this context:
1. Run Dokuwiki with PHP 8.1
2. Install the "sync" plugin
3. Run the "sync" plugin, and when prompted whether you want to keep the
remote of the local file, click to show the diff

That's it: on the window which opens to display the diff, there is a warning
saying that $INFO is null.

(Perhaps an even better fix would be to ensure that $INFO is set in this case
but at least this commit fixes this issue and shouldn't have any detrimental
side effects)

Our error handler was only logging warnings, but logging other errors,
especially those that may have been triggered by 3rd party libs, is
helpful, too. This adds a few more loggable errors.

This should especially help with composer trigerring a E_USER_ERROR when

fix autoloading for tests

This replaces my attempt in 12ebce974be688ac34bf4389645d5fc7baa29cc7

The canonical namespace for DokuWiki core tests is dokuwiki/test/ and
this is mapped to _test/tests now in the autoloader.

This means the majority of tests is in the dokuwiki/test/inc namespace.

Mockfiles are located at _test/mock and have the namespace
dokuwiki/test/mock - if that's good or bad is debatable. I simply kept
it as it always has been. But there might be an argument for having mock
objects closer to the tests that use them (eg. right next to the test
files).
