[web] **ALL** reports shown when the run filter "wildcard pattern" does NOT match ANY runs whatsoever (because typo)

[whisperity]

Describe the bug
The web UI returns all the bugs stored in the product when filtering with a run filter that is a wildcard.

CodeChecker version
6.23 release

To Reproduce
Steps to reproduce the behaviour:

https://codechecker-demo.eastus.cloudapp.azure.com/Default/reports?run=*llvm-master-csa&is-unique=off&diff-type=New

1. I filtered for *llvm-master-csa instead of *llvm-master-version_csa because I misremembered the run name pattern (runs created by the CSA-Testbench).
2. This run wildcard (the only filter) does NOT match any actual runs.
3. All 1.85M reports are returned. (It does take a while!)

Expected behaviour
Exactly 0 reports shown (and preferably this result is calculated quickly). The "baseline" runs are a kind of source, if no sources are "allowed" based on the filters, then nothing should come out of the sources.
