Fix overlapping text in headings in annotation bodies

Parent elements of annotation cards set line heights to absolute pixel
values. Annotation card headings then inherit this and as a result,
their line height is too small for the font size.

We ought to reconsider the way line heights are set elsewhere in the
app, but resetting the line height in the `styled-text` mixin ensures
that annotation body styles are protected from whatever the parent
elements do with it.

Add direct linked group to store

Add abililty to clear groups in store

- Fix minor mistake in filterGroups where directLinkedGroupId should be
set to null rather than undefined.

This is needed to be able to clear the group state when logging
out and logging in.

Use same direct-linked group error when logged-in

Get group for direct-linked ann in group service

- Fetches the direct-linked annotation's group when the direct-linked
  annotation's group is not fetched by the group.list, profile.group,
  or the direct-linked group.
- Simplify the logic in the filterGroups function and pass the
  direct-linked annotation's groupid to the filterGroups function to
  avoid a duplicate annotation fetch.
- Add tests.
This is a fix for hypothesis/product-backlog#986.

Upgrade mockable-imports Babel plugin and remove unused mock

There was a bug in previous versions of the plugin that allowed unused
mocks in certain cases.

Fix bug where direct linked group is duplicated

Do not add the direct-linked group to featuredGroups if it is already
present. This happens when a group is direct-linked to but the group
is already scoped to the page so the direct-linked group shows up twice.
