tpac: can't reactivate or change activated date for a hold through the edit hold interface

Evergreen version: 2.2 RC1

In My Account, a patron can suspend a hold by clicking to "edit" the hold, selecting the option to suspend it, and (optionally) setting an activation date. However, once the hold is suspended, there is no option through the edit holds interface to reactivate the hold or to change the activation date. The only way to manually re-activate the hold is to use the "Actions for selected holds" menu.

This is problematic for a couple of reasons. If the user suspended the hold through the "edit holds" interface, it is reasonable that they would assume they would need to take the same path to re-activate the hold.

Once the hold is suspended, there doesn't seem to be a way for a patron to change the activation date without re-activating the hold through the "Actions for selected holds" menu and then suspending it again through the "edit holds" interface. I could see a common scenario where the patron uses the wrong date format for the suspended hold. Once submitting the the form, the user is likely to immediately see that the date isn't displaying and then might be likely to try adding the date again by clicking the "edit" link. However, the only option now available for the suspended hold is a change in pickup library.
