Fix cargo odra schema wrong bin name.

[zie1ony]

If project name was generate with - like my-token, then in Cargo.toml it hash:

[[bin]]
name = "my_token_build_schema"
path = "bin/build_schema.rs"
test = false

And this is what happens:

$ cargo odra schema
💁  INFO : Generating schema files...
error: no bin target named `my-token_build_schema`

	Did you mean `my_token_build_schema`?
🤦  ERROR : Command Couldn't run cargo with args ["run", "--bin", "my-token_build_schema", "--release"] failed.

It should change - to _ when creating bin name.
