scaffold map foo fails when CreateFoo message exists

[fadeev]

To Reproduce

starport scaffold chain github.com/cosmonaut/scavenge --no-module
cd scavenge
starport scaffold module scavenge --dep bank
starport scaffold message create-scavenge solutionHash description reward
starport scaffold map scavenge solutionHash solution description reward scavenger --no-message

component type with name scavenge is already created (type MsgCreateScavenge exists)

Existing MsgCreateScavenge shouldn't prevent map (and list) with --no-message to be scaffolded.

Please provide output of commands
