Crashing on keys with dot

[KonradSwierczynski]

Hey, I spotted strange behaviour when using keys with dots which is inconsistent and can crash validating config.

See example below:

const config = convict({
  test: {
    param: {
      doc: 'some nested parameter',
      format: String,
      default: 'foo',
    },
  },
});

// Example 1
config.load({ 'test.param': 'bar' });
config.validate({ allowed: 'strict' });  // passes validation
console.log(config.get('test.param'));  // prints out 'foo' - unexpected, since previous load should set the value or fail validation
// in this example the validate would throw an error, key with dot should not be treated as path

// Example 2
config.load({ 'someOther.param': 'baz' });
config.validate({ allowed: 'warn' });  // throws error - unexpected, should just print a warning

/* the error:
Uncaught Error: cannot find configuration param 'someOther.param'
    at walk ([...]/node_modules/convict/src/main.js:2:8321)
    at flatten ([...]/node_modules/convict/src/main.js:2:1400)
    at validate ([...]/node_modules/convict/src/main.js:2:2099)
    at Object.validate (/[...]/node_modules/convict/src/main.js:2:10481)
*/

I'm using convict in version 6.2.4 and node v18.17.0.

Having the same issue, I'm trying to store react-intl messages in my config, but due to their naming I get the same failure, for example

messages: {
  doc: "Translated messages for current shop locale",
  format: Object,
  default: {
    "foo.bar": "bar",
  },
},

fails with Error: cannot find configuration param 'public.messages.foo.bar'
