problem with ios client (TUSKit), incorrect Upload-Metadata is being sent

[sjay23]

Faced such a problem. the php and js client works well and sends the correct data to Upload-Metadata.
When I use the ios client, the data is sent like this

filename MzgxREJGRkQtRkM0MS00MUNELTkwNjgtNUIyOTNBMjU4QUEy, filetype YXBwbGljYXRpb24vb2N0ZXQtc3RyZWFt - is not correct

And a 500 error is thrown. Because of the gap. Is there a way to fix this.
Because without a space everything works correctly.

filename MzgxREJGRkQtRkM0MS00MUNELTkwNjgtNUIyOTNBMjU4QUEy,filetype YXBwbGljYXRpb24vb2N0ZXQtc3RyZWFt - is correct

Screenshots

I added an example of debugging this parameter in different situations.

@sjay23 you can use 2.2-dev to try out the fix.
