NIFI-15945 - Parameter not correctly added to parameter context when having multiple suffixed parameter contexts

Summary

NIFI-15945 - Parameter not correctly added to parameter context when having multiple suffixed parameter contexts

Consider the following scenario: in a registry you have a versioned flow F at version N that represents a versioned process group attached to a parameter context P.

In NiFi, you import that flow three times with the flag that you don't want to re-use the parameter context. You get:

• F_1 with parameter context named "P"
• F_2 with parameter context named "P (1)"
• F_3 with parameter context named "P (2)"

Now consider a new version of the flow F, version n+1, where a new parameter Z is added to P.

When you upgrade F_2 or F_3 to the version n+1, the parameter Z is not added to their bounded parameter context.

Thanks for addressing this issue @pvillard31. The changes look good, just one minor recommendation on the test class.
