remove or correct @internal tag usage

[CybotTM]

at the moment IDE [PhpStorm] tells me i should not use $redis->multi()

according to phpdoc the internal tag is the opposite of the api tag - it should hide a function from external usage

using it to hide just documentation you need to use brackets around it
