Persisting TextMorph change the size of the text

[Hilaire Fernandes]

I have found this strange bug: when persisting a TextMorph (System set 
with default font to Accujen 10), when I fetch it back from the DB its 
font size is Accujen 9 and not 10 anymore

A simple code like that exposes the problem (close the session between 
the two statements to effectively get the text morph from the database):

(session addBranch: #test with: 'HELLO' asTextMorph ) openInWorld textStyle
  ==> a TextStyle Accujen10

Then fetching back after a full close of the DB:

(session branch: #test) textStyle
  ==> a TextStyle Accujen09


Any idea ?
