Remove composer minimum stability

[snapshotpl]

With composer minimum stabilty dev:

• zf and many others is loaded from master (unstable),
• loading time from branch (no tag) it's sooooo long...

👍 for also actually pinning to concrete versions, unless necessary to pin to a branch.

Have you tested this? I would expect a corrisponding composer.lock update (unless this doesn't change loaded versions).

Everything working fine: manual and unit tests. I see a huge different in speed when I run composer install becouse with stable option composer download from tag (zip), without stable download from branch.

Thanks for your time :)
