Revert "Be sensible computing project patch counts"

This reverts commit cfcf2f2a80ac0709f1a5fd9aa212c8403daa5a18.

This will no longer be necessary once we remove the Patch-Submission
split. Revert it now to avoid needing to rejig this later.

Conflicts:
	patchwork/views/project.py

NOTE(stephenfin): Conflicts are due to commit 880ec8c5 ("Fetch
maintainer information in one query") which changed nearby lines.
