Plain text updated instead of backlink if it matches the backlink text

During the replace backlinks phase of rename document, the replace will update plain text in the body if it matches the link text and is before the link. For example, if you have a page like this:

##begin document
A) Main.pagename

B) [Main.pagename]

C) pagename

D) [pagename]

##end document

Notice that A & C are not links.

Renaming Main.pagename to Main.pagename1 will update the plain text instead of the links. Giving you this:

##begin document
A) Main.Main.pagename11

B) [Main.pagename]

C) pagename

D) [pagename]

##end document

I'm using svn trunk for the other backlink fixes ( XWIKI-1028 ).
