Rabobank /PREF handling

[tomcoonen]

A small improvement could be made by parsing a description from:
/PREF/This is the payment description
to:
This is the payment description

@tomcoonen seems like this could go into the EREF handling / parsing... ? Correct? If given a PR (with test) that would be great!

[tomcoonen]

@fruitl00p will try to find some time soon :)

@tomcoonen is this still an issue?

[tomcoonen]

@fruitl00p yes, this is still occurring, 6 months fly away I see..

@tomcoonen thanks. Is there a test transaction (redacted with other values, but keeping / changing the original description?) That way i could test to see how this currently comes out and how it should come out ;)

Currently i've created a PR that might fix this, but i'd like some more test cases... ;)
