AAU OneDay site throws errors

[falkecarlsen]

Might just be a temporary bug or seasonal, as summer break is in effect.

chwifi throws this error but correctly identifies the update as failed:

/tmp/chwifi-passwords.html:6: HTML parser error : Unexpected end tag : meta
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"></meta>
                                                                              ^
XPath set is empty
Failed to update cached passwords!

AAU OneDay throws this 500 error upon logging in:

This should probably be handled better, somehow identifying whether the site is functioning properly instead of failing on unexpected input.

Note that connection is still handled fine, only the password update routine is broken.

AAU OneDay is now up again after AAU IT has fixed their network errors, and chwifi again works as intended.

Opened #30 to reflect findings.
