Initialize model with default values

[kestarumper]

Closes #1066.

Changes

• Model is initialized with the initialValues taken from schema (Bridge) -
• Model results from a shallow merge of schema.model and props.model and the latter one takes precedence
• (__tests__ only) render(...) changed wrapper from <context.Provider> to <AutoForm> because it changed behavior of <ListField> (the list of child fields was incorrect)

Notes

• BREAKING: This changes the initial render and doesn't trigger the Field.onChange of the fields that set their initialValue on the first render. However, the fields that are rendered after, e.g., after adding another field in an Array, or due to conditional rendering, will still trigger Field.onChange.
• BREAKING: Optional / Required doesn't affect setting the model

Example

• Playground (localhost)

  // SimpleSchema2Bridge
  {
  string1: {
  type: String,
  defaultValue: "yooo"
  },
  string2: {
  type: String,
  defaultValue: "yooo2",
  optional: true
  },
  friends: { type: Array, defaultValue: [{ name: "John Doe", age: 42 }] },
  'friends.$': Object,
  'friends.$.name': String,
  'friends.$.age': { type: Number, defaultValue: 99 },
  'friends.$.address': Object,
  'friends.$.address.street': { type: String, defaultValue: 'Sesame' },
  'friends.$.favoriteNumbers': { type: Array, defaultValue: [21, 37] },
  'friends.$.favoriteNumbers.$': { type: Number },
  }

Playground link doesn't work for me (I installed dependencies, built everything and started doc website). I've got this error:

TypeError: Cannot read properties of undefined (reading 'length')

Works for me. I run npm run reset && npm ci (node v20.10.0).

@kestarumper I tried it with Node v20.10 and npm 10.2.5. I ran npm run reset && npm ci. Still the same issue:

TypeError: Cannot read properties of undefined (reading 'length')

However, it is working for @Monteth.
