dolt branch --track does not create a new branch

Repro.

1. dolt clone dolthub/museum-collections
2. cd museum-collections
3. Try to create a branch with dolt branch --track doesn't work.

$ dolt branch -a
* main                                          	
  remotes/origin/json_cols                      	
  remotes/origin/main                           	
$ dolt branch --track origin/json_cols
* main                                          	
$ dolt branch -a                      
* main                                          	
  remotes/origin/json_cols                      	
  remotes/origin/main  

dolt checkout does work:

$ dolt checkout --track origin/json_cols
Switched to branch 'json_cols'
branch 'json_cols' set up to track 'origin/json_cols'.
$ dolt branch -a
* json_cols                                     	
  main                                          	
  remotes/origin/json_cols                      	
  remotes/origin/main

It looks like --track behavior is different in git branch. You use --track or -u to set the tracking branch of a branch.

But this also doesn't work in dolt:

$ dolt branch json_cols --track origin/json_cols
'json_cols' is not a valid remote ref and a branch 'origin/json_cols' cannot be created from it

This does work in Git:

$ git branch test-track --track origin/Hydrocharged-3d24c03b
branch 'test-track' set up to track 'origin/Hydrocharged-3d24c03b'.

Workaround for this is to use slightly different formatting of the command for Dolt:

dolt branch --track somebranch origin/mybranch
