[BUG] Fix internal claims tests

[temaniarpit27]

Internal claims tests fail in nightlys. Works in local when running individual tests, but fails when running all the tests with bridge spammer.
I think it is due to a lot of claims happening and tests are not able to find the claim in 1st page.

Claims are still filtered using the global index in internal claims test, so that shouldn’t be the issue.
The only explanation I can think of is that the claim hasn’t been indexed within the expected timeframe.
