Fix issue with timezones when adding new schedule

[hayesr]

When adding a new automate task schedule the value for time zones are decoded, then if a time zone contains an ampersand (like Eastern (US & Canada) the value is split on the ampersand. This change leaves the time zone encoded when sent to the server.
