feat(auto-edits): add test case for setting context (#6592)

Adds the test case for the two issues we faced:
1. Tab not working when conflicted with edit command decorations.
[Resolves
comment](#6581 (comment))
- [test cases for PR](#6581)
2. Suffix getting duplicated because in addition to inline acceptance,
we were modifying the document again on accept - [[test case for
PR](#6583)]

## Test plan
Added test case
