wasmer wasmer/wabt not working as expected (multiple commands)

[syrusakbary]

When multiple commands are found, we should show the commands available. Right now we just directly try to run one of the commands without it being the entrypoint:

➜  ~ wasmer wasmer/wabt

wat2wasm: expected filename argument.
Try '--help' for more information.

Should work with --command wabt

but yeah, we should show the commands

Seems that --command-name wabt is ignored. I'll investigate this.

No, the issue is that when multiple commands are given (unless there's an entrypoint), it should do something like:

$ wasmer run wasmer/wabt
The `wabt` package doesn't have a default entrypoint, but has multiple available commands: `wasm2wat`, `wat2wasm`, ...
You can run any of those by using the --command=COMMAND flag.
  -> wasmer run wasmer/wabt --command=wasm2wat ...

Also, we need to make sure that wapm2pirita only puts an entrypoint if there's only one command. If multiple commands are present, no default entrypoint should be set.
