fix: retry initialization

[aminya]

A simple fix for #57. Whenever this error happens, I try again and it works the second time. So I think it is better to implement the retry in the code!

Fixes #57

It is this line that is failing according to the stack traces in #57:

x-terminal/src/element.js

Line 672 in d91c0a4

this.fitAddon.fit()

we could just add a try catch and fail silently but it would be better to figure out why it is failing.

#136 might fix #57 it prevents .fit() from being called when the terminal width or height is 0

I will try that!

I will close this in favor of #136
