[BUG] Typescript bindings contracts order is random

[rsodre]

Describe the bug

Every time we generate typescript bindings, the order of methods in contracts.gen.ts is changed.
It makes it impossible to review the generated contracts.
And is terrible to track changes and update the client after contract changes.

To Reproduce

Build dojo-starter multiple times and compare the bindings.
If there was no change in the models, they should not be updated.

Expected behavior

The generated sources should be deterministic and historically accurate.
