Resolve "Redesign project lists UI: Further improvements"

Closes #55669

See merge request gitlab-org/gitlab-ce!24011

This commit, introduced in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/23812,
fixes a problem creating a displaying image diff notes when the image
is stored in LFS. The main problem was that `Gitlab::Diff::File` was
returning an invalid valid in `text?` for this kind of files.

It also fixes a rendering problem with other LFS files, like text
ones. They LFS pointer shouldn't be shown when LFS is enabled
for the project, but they were.

47d4890d changed the order of pagination so that the full list of
branches would be passed to Gitaly to determine which ones had been
merged, but this operation can timeout for large repositories with
many branches. We only need to determine whether the found branches have
been merged, so limit the scan to those.
