Impossible to sync with calcurse-caldav! "https" appended to hostname for no reason

[connor5043]

Version information. Calcurse 4.8.1, Httplib2 0.22.0

Bug description. When I run calcurse-caldav --init=keep-local I get the following error:

Connecting to [redacted].com...
Removing all objects from the CalDAV server...
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/httplib2/__init__.py", line 1343, in _conn_request

During handling of the above exception, another exception occurred:

As you can see, https has been appended to the hostname for no reason. calcurse-caldav --init=keep-remote works: although it says "Failed to import object" for all of the objects, all of them do get imported.

Reproduce. Install calcurse. Run it once, make an event for example. Make a simple config file in ~/.config/calcurse/caldav/config:

[General]
Binary = calcurse
Hostname = [redacted].com
Path = /[redacted]/[redacted]/[redacted]/[redacted]/
AuthMethod = basic
InsecureSSL = No
HTTPS = Yes
SyncFilter = cal
DryRun = No
Verbose = Yes

[Auth]
Username = [redacted]
Password = [redacted]

Run calcurse-caldav --init=keep-local. Get error

Expected Behavior. Expected to put events from local calcurse calendar into CalDAV calendar.
