RE-using an existing config (with script install) breaks MQTT upload

[geurtsd]

Issue:

• when executing the install-script AND
• when using the option to re-use an existing (the current) config THEN:
• It "breaks" the MQTT upload by not correctly reading and (re) writing the MQTT-settings / arguments

below is a copy past of the (config) line that gets "corrupted":

WORKING CFG line:

            MQTT_PublisherArgs=-u MyUser -P MyPassword -h {host} -t {topic} -m "{{message}}"

CFG file after edit via script:

            MQTT_PublisherArgs=-h -u MyUser -P MyPassword 

WORKAROUND:

• when changing settings: always start with a new config (and don't make any errors in settings .... ;-))
• edit the config file manually (but requires adjusting authorizations on the file - I prefer not to do that)

I was able to reproduce this, but only when password contains '$'
