LUCENE-9856: minor tweaks

TestAnalyzers tests doesn't need asserts, it had
SuppressWarnings("unused") the whole time, so we can revert the changes
since this is now respected.

Gradle has single quotes instead of double quotes, 30 minutes later :)


> Improve static analysis to catch dead code and other potential bugs

> When working on PR [https://github.com/apache/lucene/pull/25,] we noticed 
> that some dead code is not being caught during static analysis in gradle 
> build, such as the *start* variable in the following code: 
> [https://github.com/apache/lucene/blob/a5996dbecd4a6b4147d961260711a2cb6aeab3d3/lucene/facet/src/java/org/apache/lucene/facet/FacetsConfig.java#L446-L456]
>  
> We may need to look at if additional javac compiler flag, or configuration 
> for *error prone,* should be added to catch such bug as well as other 
> potential ones.
