Bug: Hardcoded watch patterns in cli-utils

[pavlo-liapin]

In https://github.com/ionic-team/ionic-cli/blob/master/packages/%40ionic/cli-utils/src/lib/ionic1/serve.ts#L135, it seems like it's impossible to overwrite several hardcoded patterns defined in the same file on line 15. Even after adding !www/**/* to project.watchPatterns, serve command is detecting changes in www directory. Shouldn't default patterns be used only in absence of project-specific ones, instead of conjunction?

Thanks

@pavlo-liapin I think you're right. I'll review this tomorrow!

Should be fixed in the next release! Thanks!
