Drawtext reinit command fails when using textfile

It looks like the drawtext filter populates its internal text parameter when reading from a text file and then fails to reinit, erroneously complaining that both text and textfile are provided.

To reproduce:
ffmpeg -i /tmp/bla.mp4 -filter_complex "zmq,drawtext=x=100:textfile=/tmp/content" -y /tmp/bla.flv

Then, in another console:
echo Parsed_drawtext_1 reinit x=200 | zmqsend

Error log:
[Parsed_drawtext_1 @ 0x7fbe47713e80] Both text and text file provided. Please provide only one
[Parsed_drawtext_1 @ 0x7fbe47713e80] Failed to process command. Continuing with existing parameters.
