FullClusterRestartIT#testRecovery fails on CI

[javanna]

This may be similar to #31062 but the error looks different and it happens on master, so I went for opening a new issue. I was not able to reproduce this failure.

This test failed in a short window after we upgraded to Lucene-7.5.0 in 6.x and but had not adjusted that bump in the master. This is fixed in 5decb23.
