Bug 19578: Remove MARC punctuation in notices (TT syntax)

Bug 19578: Remove MARC punctuation in notices (TT syntax)

Jenkins fails (run 287) on a test in t/db_dependent/Letters/TemplateToolkit.t:

With the historical syntax:
        # Your request for an article from tQYRS (c3Av58O0P5xkkIGu) has been canceled for the following reason:

With the TT syntax:
        # Your request for an article from tQYRS_ (c3Av58O0P5xkkIGu) has been canceled for the following reason:

The last character of the biblio's title has been removed because it's a punctuation character.
It comes from: C4::Letters::_parseletter
 893         $val =~ s/\p{P}$// if $val && $table=~/biblio/;

The same replacement is done for patron's attributes too.

Test plan:
- Confirm that the new tests pass. That should be enough to confirm this change make sense.

Test plan (manual):
- Create a biblio with a title ending with a punctuation (like "with_punctuation_"), or any other fields of biblio/biblioitem
- Generate a notice which will display this field (CHECKIN for instance)

Use the historical syntax and the TT syntax, both should display the title without the punctuation character at the end

CHECKIN historical:
The following items have been checked in:
----
<<biblio.title>>
----

CHECKIN TT syntax:
The following items have been checked in:
----
[% biblio.title %]
----
