When a deployment has no files to show in the dropdown we
fallback to the regular single button for the review app link.

This commit moves the review app link into a component since it's
used twice.

This fixes a bug where a discussion on a none changed line
would not get fully removed and therefore leave the comment row
empty. This was caused by the discussiob being added
to the right when it shouldnt of been

This also fixes a very rare edge case where discussions would get added
twice to diff lines causing a Vue rendering warning

This gives flexiblity to avoid duplicated query of Project.

Extract language_from_git_attributes as a concern so it can
ben included in two blob classes.

This is to DRY the repeated file size check.

Move spec and constants to Highlight

This replaces the repository param.
This allows more flexiblity as sometimes we have highlight content
not related to repository. Sometimes we know ahead of time the language
of the content. Lastly language determination seems better fit as a
logic in the Blob class.
`repository` param is only used to determine the language, which seems
to be the responsiblity of Blob.

Force FoundBlob to use BlobPresenter

Ported from Highlight class since it as a concept is more related to
blob, and this allows more flexibility.

seed_helper changed because testing requires attributes file in repo,
but repo was not a real git repo but instead faked.

Add an index to the `file_store` column on `lfs_objects`. This makes
counting local objects faster.

Also, there is no longer need to check for objects with `file_store`
being `NULL`. See
