Updated help text for trends to match actual amount returned.

[smalleel]

When running "t --help" or "t help trends", the help text states that it will return 10 trends, but it actually returns 50. I updated the help text accordingly. For bug #337

Weirdly, RuboCop seems to be getting caught on a few issues that weren't effected by this commit.

Offenses:

I saw RuboCop was having similar issues with other pull requests as well, for example: #320

Was RuboCop updated at some point and is now upset with some pre-existing items in the source? I see that in the gemfile on line 17 is specifies any version >= 0.37. If the issue is with RuboCop becoming more stringent, would it be okay for me to submit a pull request addressing the issues RuboCop is upset with? Or any insight into what else may be causing this?
