StRewriterApplyRuleOnAllClassesCommand>>#execute fails to raise confirmation correctly

[ericwinger]

To Reproduce
I opened the Rewrite Rule Editor and tried to transform two expressions. Pressed Transform all classes and got a confirmation message: "This process can take between 1 and 2 minutes.". Hitting Yes, I got the attached stack.

Expected behavior
No walkback

Screenshots

Version information:
Pharo 12.0.0
Build information: Pharo-12.0.0+SNAPSHOT.build.1523.sha.3fd20c14be4ec63710f40bb8eb486e1eaf262af2 (64 Bit)

Expected development cost
Looks pretty easy to fix

Additional context
I could continue with the transform by do'ing the rest of the code in the StRewriterApplyRuleOnAllClassesCommand>>#execute.
