Automerge: [LLDB][PDB] Relax check for resolving breakpoint (#169932)

The test was flaky, because it assumed that the breakpoint was always
resolved before `r` was executed
(llvm/llvm-project#169728 (comment)).
This PR removes the check for this order. It still checks that the
breakpoint is resolved before it is hit.
