exports.process function works incorrectly if instrumentedSource contains "parent directory" pattern

[KozhinM]

Hi,
We are using grunt-template-jasmine-istanbul in dash.js project and we recently faced the following issue:
In scr/main/js/template.js there is exports.process function. It has a check at line #193:

    if (!grunt.file.isMatch(files, instrumentedSource)) {
        return;
    }

Where var files = context.options.files || '**/*';
 
If files = '**/*' and instrumentedSource contains a "parent directory" pattern, e.g. '../someFile.js' the result of the grunt.file.isMatch function is always false. Thus, the function always returns right after the check and never goes farther.
 
We were able to fix it locally this way:
• Replace the pattern with '*.*'
• Add {matchBase: true} option as a first parameter of isMatch function

We found out that the issue was introduced by this commit:

The intention of '**/*' was that it matches any path, so this is definitely a bug. I am a bit surprised that this doesn't work with parent directories. We need to find out which pattern needs to be used and some tests.
