connectAndLogin not working

[IlyaSemenov]

connectAndLogin crashes:

(node:58749) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'exec' of undefined
    at Client._sendIpcCommand (/.../node_modules/tdl-multiprocess/lib/Client.js:114:37)
    at Client.connectAndLogin (/.../node_modules/tdl-multiprocess/lib/Client.js:93:17)

the current proxy implementation is clearly incorrect:

tdl-multiprocess/lib/Client.js

Lines 92 to 94 in 01fde12

	connectAndLogin() {
	return this._sendIpcCommand('connectAndLogin')
	}

tdl-multiprocess/lib/Client.js

Lines 112 to 114 in 01fde12

	async _sendIpcCommand(command, arg) {
	const sArg = !!arg ? JSON.stringify(arg): undefined
	const response = await this.ipc.exec(command, sArg)

because this._ipc is only constructed in login.
