Correction Alembic script

I corrected the script by putting server_default value to the empty string.

changed milestone to %0.4: Tests and studies improvements

added Studies & tests To do labels

Could you rebase upon dev? As we merged your previous PR, there is a merge conflict with it. Also, you set a server_default but your model doesn't have a default value. So you should choose between:

• keep the server_default and set a default value on your columns in the model also.
• drop the server_default once the migration done.

Sorry for the mistake, I just pushed a fix. I also realize that I didn't update the API call when updating a study, so I fixed that as well.
