successful during db connect.  This allows the module cache to construct
without errors when run from msfconsole.

Merge branch 'bug/deprecation-warning-logging' into feature/module-cache-construction

MSP-8994

Conflicts:
	Gemfile

bug/run-seeds was merged into bug/deprecation-warning-logging after
bug/deprecation-warning-logging was merged into
feature/module-cache-construction, so bug/run-seeds still needs to be
merged to feature/module-cache-construction as this commit is doing.
