Quill-mention does not consider the searchterm which contains the mentiondenotationchar as a single term.

[dgraceli]

Actual: In the text editor, if user types @daisy@ftc.gov, it considers only 'daisy' as the searchterm. and ignores the string after the '@'.
Expected: I want quill-mention to consider 'daisy@ftc.gov' as a single searchterm and provide search results for the same.
