[BUG] Unneeded output when creating keys

[thomastaylor312]

Describe the bug

When running wash build (or any step that generates a key for you), this output is written to the terminal:

{"keygen":"true","path":"/Users/taylor/.wash/keys/blahblahblah_module.nk","status":"No keypair found"}

That message shouldn't be written by default (probably should just be logged)

To Reproduce

• Create an actor with a name you haven't used before: wash new actor -t hello blahblahblah && cd blahblahblah
• wash build
• See output

Expected behavior

The "no keypair found" should not be echoed to the terminal
