Subject: [PATCH] Show repo activities even if only code unit active or git
 repo is empty but issue is active (#3455)

When all repository units are deactivated except for the code unit, the activity tab will not be shown.
Since the activities tab also shows contributing stats, it would be good to show the activities tab also when only code is active.
This commit changes the behavior when the activities tab is shown.
Previous it would only be shown when Issues, Pull-Requests or Releases are activated. Now it would additionally be shown when the code unit is activated.

Refs: #3429
