Add userCollectionName to Mongo object in @accounts/mongo or fix precedence in @accounts/database-mongo-password

[orenteriab]

The property userCollectionName is not part of the Mongo options in the package @accounts/mongo.

I'm using:

 "@accounts/mongo": "^0.34.0",
 "@accounts/password": "^0.32.0",

I even get the error on TS end, that userCollectionName is not part of Mongo object:

Although, the above code runs perfectly, I get that error from TS.

I think, in case you don't want to expose userCollectionName in Mongo object of @accounts/mongo, the precedence for it should be:
1.- userCollectionName in options param.
2.- collectionName in options param.
3.- userCollectionName in defaultOptions.

Here's the current code:

accounts/packages/database-mongo-password/src/mongo-password.ts

Lines 81 to 85 in ff983b8

	this.options = {
	...defaultOptions,
	...options,
	timestamps: { ...defaultOptions.timestamps, ...options.timestamps },
	};

My suggestions would be something like:

constructor(options: MongoServicePasswordOptions) {
    this.options = {
      ...defaultOptions,
      userCollectionName: options.userCollectionName ||
        options.collectionName || defaultOptions.userCollectionName,
      ...options,
      timestamps: { ...defaultOptions.timestamps, ...options.timestamps },
    };

Thanks in advance.
