load dir-locals before switching project

[ericdanan]

Modified function projectile-switch-project-by-name. Instead of calling switch-project-action from the current buffer, this is done in a temporary buffer after calling hack-dir-local-variables-non-file-buffer.

I think this fixes #413 and #1005 . It is the same solution I proposed there, but maybe easier to test for you with a PR.

Sorry I don't know how to add tests or make test. I don't think the changelog or readme should be updated since the function is not "visible".

Thanks

I'd add some comments explaining here the need for this.

Messing with the default-directory is a very bad idea. Just let-bind it.

Done, thanks.
