Keyword not found recommendations

For issue #888.
For your test question, I have this test:
```
------------------------------------------------------------------------------
Run Implicit Missing Keyword Similar To Both Libraries :: FAIL No ... | FAIL |
No keyword with name 'kkeyword in both libraries' found. Did you mean:
    RecLibrary1.Keyword In Both Libraries
    Rec Library 2 With Custom Name.Keyword In Both Libraries
------------------------------------------------------------------------------
