Add jQuery matchers to Jest

This allows us to set the encoding of an IO passed without reading it
into memory.

This is useful if we want to stream files into Gitaly. Like we do when
uploading a new file to the repository.

Allow extra permissions in Project & Issue GraphQL types

Adds `# frozen_string_literal: true` to spec/workers ruby files

During a project import, it's possible that new branches are created by
the importer to handle pull requests that have been created from forked
projects, which would increment the `pushes_since_gc` value via
`HousekeepingService.increment!` before a full garbage collection gets
to run. This causes HousekeepingService to skip the full `git gc` and
move to the incremental repack mode. To ensure that a garbage collection
is run to pack refs and objects, explicitly execute the task.

Add # frozen_string_literal to spec/models

See merge request gitlab-org/gitlab-ce!26791

This makes sure we load the page as part of the spec, instead of a
before block. So we could still perform setup inside shared examples,
avoiding failures caught by data being wrongly cached when loading the
page multiple times during a single spec
