Fixing error type by wrapping in String()

removing enableRemoteModule from BrowserWindow Electron module

last mentions in the docs:
https://www.electronjs.org/blog/electron-10-0#breaking-changes

Why?
https://www.electronjs.org/docs/latest/breaking-changes#default-changed-enableremotemodule-defaults-to-false

We recommend moving away from the remote module.

And figured out how to access a height and width property by following docs

Further Updating getUserMedia
https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia
outdated API for getting media streams from the user's device. The mandatory object and properties like chromeMediaSource are specific to older implementations and may not be compatible with modern browsers.

@Pfed-prog thank you for opening this, but we can't accept this PR in the current form:

• these getUserMedia and BrowserWindow fixes should be separate PRs. It is time-consuming to review when you have thousands of unrelated lines changed in this PR due to linter.
  • please remove these changes from this linter PR, and open a new PR per each of them.
• the linter fixes are fine, as long you remove dependency on aegir and only depend on linter. (adding 30k of lines to package-lock.json just for linter does not feel acceptable)
