Terminalizer exits straight after starting recording.

Below happens when starting recording, rapidly goes through started>finished>share without recording anything.

``` terminal
user@ThinkPad:~/termin$ node node_modules/terminalizer/app.js record demo
The recording session is started
Press CTRL+D to exit and save the recording
Successfully Recorded
The recording data is saved into the file:
/home/user/termin/demo.yml
You can edit the file and even change the configurations.

Let's now share your recording on https://terminalizer.com

Reproduce `node node_modules/terminalizer/app.js record demo` with Node v12.13.1, then inspect `node_modules/terminalizer/commands/share.js` at line 199 and the record/play entry points in `app.js`. Done means recording does not immediately finish, `play demo` produces the saved recording, and sharing no longer raises the reported `TypeError`.
