Take result of find and make boolean

[paul90]

Take the result of find and make it true/false rather than the found value or undefined if there isn't a match.

Provides a fix for beakerbrowser/fritter#17

[paul90]

What was happening is that the find record.mentions.find(x => { return x.url == inst.userUrl }) is either giving us the firstx where the test x.url == inst.userUrl is true, or the find is giving us an undefined.

This means that the result of calling isAMentionOfUser(record) is:

• false - if record does not contain mentions
• undefined - if record contains mentions but not for the user
• an object the matching element from the the mentions list - if the record contains mentions and it is for the user

The fix is to not a test on if the find is undefined, giving us true if there is a mention of the user, and false if there isn't.

Good catch. It might not be an issue except that the usage is checking explicitly for false: if (isAMentionOfUser(record) === false) return.
