The names of the decorators are lost in the MetadataStorage

See original GitHub issue

Description

Since the 0.12.x update, the names of the decorators are lost when stored. For example, when the IsString decorator is used, the metadata store a new entry with the type customValidation instead of isString. This seems to apply to all decorators, because of this line: https://github.com/typestack/class-validator/blob/1955250de64d76504df465aa02076a2e5b219bb7/src/register-decorator.ts#L80.

Reproduction

Inspect the stored metadata with getMetadataStorage().getTargetValidationMetadatas and you’ll see that all entries’ types are customValidation, instead of their decorator names.

Environment

nodejs: 10.18.1
browser: no
framework/library: standalone

class-validator version: 0.12.2
