client: Fix lost unsaved highlights on Import

Save highlights before importing if changes exist to avoid losing
any unsaved rules when loading the highlight rule list from the
client.

Test case:
1.  Have at least 1 local highlight rule
2.  Add remote highlight rule, don't save
3.  Import local highlights
4.  Unsaved highlight rule gets deleted
