Update test (#495)

with issue #103 being closed the "pending" annotation can be removed
from the test and the proper result added.

I assume that the output of abbreviated titles is on purpose?
So, given this input:
```xml
<titleStmt xmlns='http://www.tei-c.org/ns/1.0'>
    <?prüfen?>
    <title type='abbreviated'><identifier>P1-PA<rend rend='sup'>1</rend></identifier> – Autographe Partitur</title>
    <title type='main'>Autographe Partitur</title>
    <title type='sub'>Manifestation</title>
</titleStmt>
```

the output of `eutil:getLocalizedTitle#2` will be "P1-PA1 – Autographe
Partitur".

Refs #103
