Fix check if a path argument is passed to occ files:scan

I was getting a lot of these in my logs for no apparent reason, and file
uploads were failing:

	{"app":"webdav","message":"Sabre\\DAV\\Exception\\ServiceUnavailable: ","level":4,"time":"2015-01-06T15:33:39+00:00"}

In order to debug it, I had to add unique messages to all the places where
this exception was thrown, to identify which one it was, and that made the
logs much more useful:

	{"app":"webdav","message":"Sabre\\DAV\\Exception\\ServiceUnavailable: Encryption is disabled","level":4,"time":"2015-01-06T15:36:47+00:00"}

Fix JS asset generation

This allows the directory where CSS/JS asset collections are
written to be changed, in case SERVERROOT is not writeable. Note
it does *not* allow the expected URL to be changed: whatever
directory is used, the server must be configured to serve it
at WEBROOT/assets. It may be possible to add another config
parameter to allow the admin to specify a custom asset URL,
but I thought I'd keep the first implementation simple.

Fix undefined variable and write unit tests for OC_Principal connector

At some point SeparatorFilter should be included upstream
(kriswallsmith/assetic), then lib/private/assetic/separatorfilter.php can be
removed and the `use` in lib/private/templatelayout.php rewritten.

SeparatorFilter inserts a separator between assets, preventing issues when
files are incorrectly terminated. For JS this is a semicolon.
