[FIX] web: action before field willStart end

On a re-render, when:

- a field is not yet started (still in willStart because of RPC)
- then an action is executed

we can get a traceback because we try to save the field before it is
started and `this.el` is not set.

eg. in MRP on a work order:

- click on + to get new serial number

=> page is re-rendered with RPC call to update duration to
   mrp.workcenter.productivity().search_read to update time
   counter

- click on "Record production" before RPC is finished

=> traceback because we try to save `duration` that is not already
started (`this.$el.toggleClass` when `this.$el` is `undefined`)

Without change, added test fails with:

  "Cannot read property 'toggleClass' of undefined"
  in BasicRenderer.canBeSaved

  "Expected 6 assertions, but 5 were run"

Before saas-11.3 5faec34a3c this.el was always set in `init` so this
issue did not happen.
