reconfigure from lightweight checkout to checkout don't pull tags from master branch

bzr 1.1rc1. I had one lightweight checkout from bzr smart server. Then I decided to convert it to full checkout (with full history on my local machine). After running `bzr reconfigure --checkout` I realized that all my tags is gone.

Steps to reproduce:

C:\Temp\3>bzr init a
C:\Temp\3>cd a
C:\Temp\3\a>
C:\Temp\3\a>bzr mkdir dir
added dir
C:\Temp\3\a>bzr ci -m 1
Committing to: C:/Temp/3/a/
added dir
Committed revision 1.
C:\Temp\3\a>bzr tag foo
Created tag foo.
C:\Temp\3\a>bzr co --lightweight . b
C:\Temp\3\a>cd b
C:\Temp\3\a\b>
C:\Temp\3\a\b>bzr tags
foo 1
C:\Temp\3\a\b>bzr reconfigure --checkout
C:\Temp\3\a\b>bzr tags
<empty output here>
