Improve error handling

Convert to our wrapper class for assertions

Check whether http://macedir.org/entity-category is set in the EntityAttributes
before using it as argument in in_array(). This prevents a "TypeError:
in_array() expects parameter 2 to be array, null given" error.

This situation happens when we do have EntityAttributes in the metadata but
none of type "http://macedir.org/entity-category". An example is an IdP
supporting https://refeds.org/category/research-and-scholarship, which would
have "http://macedir.org/entity-category-support" but not per se also
"http://macedir.org/entity-category".

Issue #1272 - SSP refuses to use temp dir if it doesn't own it, even though it can write to it (#1314)

* Issue #1272 - SSP refuses to use temp dir if it doesn't own it, even though it can write to it
This has been addressed using the is_writable function instead of checking for UID, which only works in a Linux environment

* Migrate assertions to Webmozart

This makes it mirror how it used to work and how the twig templates
work. The solution is not pretty, but the longer term solution is to
just get rid of the oldui exception.

Also actually run the existing EMail unit tests. That might have
caught this.

Closes: #1269

People might do this in the past to get correct metadata (thereby
breaking other email related functions). But our metadata generator
will now take care of this, so we can just ignore any mailto: prefix.
