Adding a new frame with the same name as an existing frame to Texture results in incorrect frame count

[BigZaphod]

Phaser: 3.16.2

Texture's add() function to add a new frame increments the texture's frameTotal variable even if the given name already exists in the texture. It doesn't check to make sure the name is actually unique first. The code probably should just check for this case before deciding to increment the counter.
