Bank module's exported genesis validation fails after denom creation in tokenfactory module

[madrezaz]

Background

In tokenfactory's createDenomAfterValidation function, a metadata is set for the denom that is being created with the following format:

denomMetaData := banktypes.Metadata{
	DenomUnits: []*banktypes.DenomUnit{{
		Denom:    denom,
		Exponent: 0,
	}},
	Base: denom,
}

in which the name, symbol and display fields are not set. In this case, bank module's exported genesis' validation will fail since it validates that the mentioned fields are not empty.

Suggested Design

The name, symbol and display fields of metadata should be set.

Acceptance Criteria

All existing and new tests should pass
