Flip value and initial for dynamic challenges to better support ctfcli (#1921)

* Makes the initial value for a dynamic challenge provided by the `initial` argument instead of the `value` argument. This makes it easier to support ctfcli. Refer to https://github.com/CTFd/ctfcli/issues/13. 
* Closes #1875
