Error when replying image message sent by myself

[guilhermebkel]

Describe the bug
Right after sending a image message and replying it I've got an error. After restarting the session and attempting to reply the image message again, it works like a charm.

Steps to Reproduce

const messageId = await client.sendFile(userId, imageBase64, "image.png", null, null, true, false)

const replyMessageId = await client.reply(userId, "image reply", messageId)

console.log(replyMessageId) // ERROR: Something went wrong while trying to send the message: ERROR_UNKNOWN

Expected behavior
Since right after sending file message (per example: video, text, audio, voice) and replying it, everything works fine, it was expected to be the same with image message.

@guilhermebkel can you add a caption to the image and try again. That, for some reason, is fixing it for me.

[smashah]

@guilhermebkel this is happening because the caption is null, if it was undefined it would work fine. I will submit a patch that will convert any caption to undefined if null is provided.

[smashah]

This should be patched now. Please restart your sessions and try again, let me know if it keeps happening. thanks

@smashah Got it! I just tested and it worked like a charm, thanks!
