This reverts commit 210d904. We revert this because, this allows the instance to persist through a powershell session across multiple pssa invocations. This is allows us to reuse the command info cache across multiple pssa invocations.
Since, helper is a singleton that persists through multiple pssa invocation, in a given powershell session, this helps us reuse the commandinfo cache created during the first pssa invocation. Results in significant perf improvement for subsequent pssa invocations.

Didn't this null check cause some other bug we saw recently?

Yes it did cause some issue earlier - Get-ScriptAnalyzer command would instantiate Helper.Instance to new Helper() and when Invoke-ScriptAnalyzer would try to set the instance again, it would ignore the setter, which cause Invoke-ScriptAnalyzer to crash.
But after adding this, that bug was resolved and the removing this null check was redundant.
