CLDC-2361 Extract bulk upload filter from session (#1617)

# Context

- https://digital.dclg.gov.uk/jira/browse/CLDC-2361
- When fixing inline for sales bulk uploads users need to be able to show only logs related to the bulk upload therefore have the bulk upload filter applied

# Changes

- After a sales bulk upload the session is set with bulk upload filter
- When viewing sales log ensure we extract this apply as a filter

# Issues

- The current implementation is globally shared between lettings and sales therefore there are issues when switching between the 2 areas
- There is a backlog ticket to refactor the filter and recommend fixing this issue then
