fix(esp-open-rtos): program hangs creating task

[MarcoMiretti]

When creating a task, after several calls to websocket_write (inside a task, not a callback) the communication is aborted, and the program appears to fail creating the new task according to the selected uri. A change in the quantity of attempts was observed.

With 256 stack each task, the problem presented itself after 15 calls. With 1024 stack each task, the problem appeared after only 4 calls (the pattern is clear). This was independent of the not-websocket-calling task, which continued to work flawlessly, regarding of the problem on the other tasks.

This was workarrounded by not calling websocket_write inside the task but only in callbacks, for our purpose, is more than enough.

this was only done for the classic controller task, but should also be fixed in ping task
