Description of problem:

Earlier I logged a defect[1] against katelo-cli as package filters were not working. Then later got to know that there is already a bug in pulp, which has already been fixed in pulp 0.251 build as per defect[2].

[1] https://bugzilla.redhat.com/show_bug.cgi?id=754021
[2] https://bugzilla.redhat.com/show_bug.cgi?id=754807

Now package filters are working from cli but not from webUI.

Version-Release number of selected component (if applicable):

How reproducible:
always

Steps to Reproduce:
1. create a new env say: test
2. create a provider 'fedora' of type custom
3. Create a product pulp and withing that a repo 'pulp_x86_64'
4. sync the repo
5. create a filter
6. Add packages to filter and Select proudct/repo to apply filter on
5. create a changeset
6. Add product,
7 review & promote changeset

Actual results:
The complete product is getting promoted to next env without blacklisted the
selected packages. 

Expected results:
filters should work while product promotion


Additional info:

I tried package filters from cli and then from webUI and found a difference in following logs:

filter=['pulp_fil']  <--- this happens when we apply filters from cli, and here pulp_fil is the name of filter.

filter=[]  <--- when we apply filter from UI.


from cli:
