join drops tags on the floor

[Matthew Fuller]

When `bzr join` attaches a branch, it doesn't bring over that branch's tags, which disappear off into the ether.

Output of script:
[...]
+ /usr/local/bin/bzr --no-plugins --no-aliases tag B1_TAG
Created tag B1_TAG.
+ /usr/local/bin/bzr --no-plugins --no-aliases tags -d B
B1_TAG 1
+ /usr/local/bin/bzr --no-plugins --no-aliases join B
renamed file:///tmp/bzr/t/A/B/.bzr to .bzr.retired.0
+ /usr/local/bin/bzr --no-plugins --no-aliases ci -m join
Committing to: /tmp/bzr/t/A/
added B
Committed revision 2.
+ /usr/local/bin/bzr --no-plugins --no-aliases tags
[nothing]

Script:

#!/bin/sh -x
bzr="/usr/local/bin/bzr --no-plugins --no-aliases"

${bzr} init A

 # Setup
 cd A ; \
 ${bzr} ci --unchanged -m a1 ; \
 ${bzr} init B ; \

  ${bzr} tag B1_TAG ; \

 # See tag
 ${bzr} tags -d B ; \

 ${bzr} join B ; \
 ${bzr} ci -m join ; \

 # No see tag
 ${bzr} tags
)

I guess this is closely related to bug 309682. If we're lucky it's already fixed by <https://code.launchpad.net/~spiv/bzr/fetch-tags-from-non-sprout-too/+merge/42911>.

We're not lucky :(
