Adding tests for rules 7-17 of dart language
Browse files Browse the repository at this point in the history 
Note that in the HS-DART-8 rule, I increased the accuracy of the rule to only get logs that have string concatenation or string format.
Note too the HS-DART-15 rule was not working because there is no capitalized property so I added the option to include it in the entire regular expression.
