Bugfix: "merge" transactions not correctly viewed with RT 3.0.8 (and before?)

Hello,

I found that Ticket merges were not correctly shown in the ticket history
(description string missing) and by further investigation that they were
not correctly entered into the database (NULL instead of “MergedInto”) in
the “Field” Column.

Attached is a fix for both. It cannot fix already existing entry in the
transaction table of the database but ensures that new entries will be
correct.

Dirk.
