Full reset doesn't work, if there is no config.json

[g-regor]

Holding down the TRIGGER_GPIO button down, doesn't erase the config (WiFi credentials and the filesystem) and then run the WiFi manager, if config.json doesn't exits.
Since the WiFi credentials are still present, WiFi manager doesn't run and is impossible to configure the gateway which would create config.json.

Steps to reproduce the behavior:

1. Upload firmware (V1.7.0) with TRIGGER_GPIO feature enabled and invalid MQTT_SERVER set.
2. Setup the gateway through WiFi manager
3. Wipe gateway's filesystem
4. Now it fails to connect to MQTT broker, but connects to WiFi
5. Hold down the TRIGGER_GPIO
6. WiFi manager's AP is never started

WiFi credentials should be erased, even if config.json doesn't exist.

Additional context
I uploaded newer firmware on a NodeMCU-32s module, that was previously running an older version (v0.9.6), so it already had WiFi credentials stored, but config.json wasn't present (new partitioning probably wiped it).

The same problem probably shows up, if you flash it on a board that was previously used for a different project and still has valid WiFi credentials.
