EE: Fix direct_upload when records with null file_store are used

Fix Epic timeline bar misalignment when start date is in last timeframe month and end date is out of range

Closes #5658

See merge request gitlab-org/gitlab-ee!5360

Old records have a null value of file_store column.
This causes the problems with current direct_upload implementation,
as this makes it to choose Store::REMOTE instead of Store::LOCAL.

This change moves the store save when change saving the object.

Ee 41059 calculate artifact size more efficiently

See merge request gitlab-org/gitlab-ee!5157

Previously we scheduled a worker to just some this but we were running
into performance issues when the build table was getting too large. So
now we've updated the code such that this column is updated immediately
and incremented/decremented by the correct amount whenever artifacts are
created or deleted.

We've also added the performance optimization that we do not update this
statistic if a project is deleted because it could result in many
updates for a project with many builds.

Port Group member contribution analytics table to Vue

Closes #4949

See merge request gitlab-org/gitlab-ee!5269

This reverts the addition of the "goldiloader" Gem and all use of it.
While this Gem is very promising it's causing a variety of problems on
GitLab.com due to it eager-loading too much data in places where we
don't expect/can handle this. At least for the time being this means we
have to go back to manually fixing N+1 query problems, but at least
those should not cause a negative impact on availability.
