Community categories shown on software page before membership is approved

[dmijatovic]

Bug:
After requesting membership to a community and selecting the categories during this process, selected community categories are shown on the software page when community membership is in "pending" or even "rejected" stage.

Expected behavior:
Community categories should be shown after the community membership is approved by community maintainer

This is on purpose, so that community maintainers can properly audit the software page before accepting or rejecting.
