URL encoded password not accepted with "-L" mosquitto_pub

[kmwoley]

I would expect a URL encoded password to be accepted with the "-L" option.

Repro:

1. Set a password with a character that requires encoding, such as p@ssword
2. Publish a message using the -L flag, with the password properly URI encoded. Example: mosquitto_pub -L "mqtt:https://mosquitto:p%[email protected]:1883/topic/phone" -m hello

Result: Connection error: Connection Refused: not authorised.

Note, passing the password (unencoded) works fine with the -P switch:
mosquitto_pub -u mosquitto -P p@ssword -h 10.1.1.10 -p 1883 -t topic/phone -m hello

Found on mosquitto_pub version 1.6.7 running on libmosquitto 1.6.7.
