Handle dependencies when updating extensions

[McNetic]

Currently, when selecting extensions in the extension manager (selecting the checkbox) and updating the extension with the button below all extensions ("Markierte Erweiterungen aktualisieren") does not check for dependencies in the updated extension, so if the dependencies changed, the new extensions the current extension depends on will not be installed.

That is not a Contao Core functionality, but +1 anyway ;-)

@contao/workgroup-repository @contao/workgroup-core I think I finally got it. Please see 8015dcc.

The fix has been merged into the version 3.0.0 release branch in 0e8190a, however, it has neither been tested/confirmed here nor there :(

I tried it one time, it seems to be working, but I not fully tested it, thats because I not respond for this...

[leofeyer]

Any tests made meanwhile?
