Assign to properties with explicit self in encode(to encoder: any Encoder)

[Dragna]

Motivation

The generated encode(to encoder: any Encoder) assigns to properties without using explicit self. This is a problem because it can produce conflicts with the local variables created in the function, e.g. the encoding container, which will then fail to compile for schemas with properties named container, as found in #695.

Modifications

• Assign to properties with explicit self in encode(to encoder: any Encoder)

Test Plan

• Update the reference tests.

@simonjbeaumont it seems to be working on my project with this change, sadly I didn't know what updates I should make for the snippet tests 😕. I you have any insight on this that would be helpful 🙏 .

Well done! 👏

@Dragna thanks for taking the time to put the patch up. I think we raced on this one. There's another PR up which adds the relevant snippet and reference tests: #699.
