Allow pasting commits multiple times

[stefanhaller]

• PR Description

After pasting commits, hide the cherry-pick status (i.e. remove the "x commits copied" status in the lower right corner, and hide the blue selection of the copied commits). However, keep the copied commits around so that it's possible to paste them again. This can be useful e.g. to backport a bugfix to multiple major version release branches.

Discussed in #3198.

• Please check if the PR fulfills these requirements

• Cheatsheets are up-to-date (run go generate ./...)

• Text is internationalised (see here)
• If a new UserConfig entry was added, make sure it can be hot-reloaded (see here)
• Docs have been updated if necessary
• You've read through your own file changes for silly mistakes etc
