[gui] Setting review status on multiple reports without returning to report list does not put "false positive" reports under "CLOSED" directory

[whisperity]

Describe the bug
When changing the review status of a bug to something like "false positive", it is moved into the Closed directory, but ONLY for the first such closed bug.

CodeChecker version
6.24.0

To Reproduce
Steps to reproduce the behaviour:

1. Open a report from a file that has more than 1 reports.
2. Suppose all of them have review status "UNREVIEWED" and are in the Outstanding directory.
3. Click on the review status drop-down and select something else, like "FALSE POSITIVE".
4. Save the status change.
5. The LHS bug tree refreshes and now the bug we just changed is moved to the Closed directory.
6. Select another bug from the Outstanding directory.
7. Repeat steps 3 and 4.
8. Step 5 now does not happen, and there is a "FALSE POSITIVE" bug report in the Outstanding directory.
9. GOTO 6

Expected behaviour
Reports are re-organised consistently.
