created and lastUsed keys exist for never used or converted profiles and have 1970-01-01T00:00:00.002Z as value

Affected version: 2.0.757 (Windows)

The bug

Profiles which have never been used have a lastUsed key in the launcher_profiles.json file. Converted profiles also have a created key.
This might be intended, but the strange thing is that their value is 1970-01-01T00:00:00.002Z. 1970-01-01T00:00:00.000Z would probably make more sense.
