[Gulp-Sass] Improper filtering of partials when #compiled is placed after compilation.

[MarkL4YG]

Since v1.0.1/v1.0.2, we declare files as compiled when they are piped through #reportCompiled().
As this is desired to be done AFTER Sass compilation so Sass errors do not mark a file as compiled, we have trouble with partials:

When piped to gulp-sass, they are consumed and removed from the stream.

  if (path.basename(file.path).indexOf('_') === 0) {
    return cb();
  }

That causes them to be never considered as compiled as they are no longer in the stream.

We need a solution to this issue.
A discussion with the gulp-sass maintainers about this may also be required.
Until then, placing the #reportCompile() before the sass call will work around that issue.

It is also necessary to evaluate whether or not this even is an issue as gulp-sass will not invoke compilation anyways due to the same code part.
Displaying a one-time heads-up message may be enough to make users aware about the improper filtering of partials.
Tracking and dependency checks however should not be impacted by this.
