Shared place - colored tokens are confused

[Jiri Srba]

Open the attached net, go to the component "new" and double click
on the place P0. Now say it is shared (and initially it suggest the
button shared place name) but change it to lift shared place instead.
However, the 10 tokens from the button place remains in the lift place
even after it is changed (and so wrong type of tokens are assigned
to the lift place now).

The net only opens in this branch

Here is a net that opens in cpn branch and shows the same issue.
Just go to the component "new" and double click the only place there.
Now change the shared place name from place_prod to place_prod2. It
changes the color type but the token in the place does not get updated
to the tokens from place_prod2. After exiting the place dialog, it still has
the wrong token.
