Searches with Hyphens Don't Highlight Search Term in Note

#### Steps to reproduce
1. Add a hyphenated word or phone number into a note (for instance, `bonus-content`)
2. Search for a part of that word or phone number with the hyphen (i.e., `bonus-`), or the entire string (`bonus-content`)

#### What I expected
Like searching for other text in a note, the search would show the content highlighted in the note

#### What happened instead
Note appears in search results, but content that I searched for isn't highlighted in the note when I open it from the results list

#### Simplenote version
4.7.0

#### iOS version
12.2

Reproduce the issue in the iOS app using searches such as `bonus-` and `bonus-content` against notes containing hyphenated text. Trace how search results open a note and how the queried text is highlighted. Done means hyphenated words and phone numbers are highlighted consistently when opened from search results.
