unique() throws depending on generator

[nicolaiskogheim]

This works as expected:

$faker->unique()->words($nb = 3, $asText = true)

This does not:

$faker->unique()->words($nb = 3, $asText = false)

Stacktrace from the latter:

  [ErrorException]                                                                
  array_key_exists(): The first argument should be either a string or an integer  


Exception trace:
 () at /data/vendor/fzaninotto/faker/src/Faker/UniqueGenerator.php:44
 Illuminate\Foundation\Bootstrap\HandleExceptions->handleError() at n/a:n/a
 array_key_exists() at /data/vendor/fzaninotto/faker/src/Faker/UniqueGenerator.php:44

It may be that I just don't understand how unique works, but I was surprised that I got this error.

This was already fixed in #749, please test the master branch.

Sorry, I should've done that. Thanks.
