api: errors when clearing a share

[bjornars]

When clearing a share of a plot, we get an extra HTTP request and some errors. The actual clearing works, but it is a bit noisy.

Python session:

In [13]: p.shared = 'public'

In [14]: p.shared = ''
<Response [405]>
PUT: https://api.novem.io/v1/vis/plots/weather/shared/
body

{
  "message": "PUT is not allowed"
}

should raise a general error

Probably need to check for an empty set here, both for add and delete:

novem-python/novem/vis/shared.py

Lines 46 to 53 in a267ef5

	rms = set(es) - set(shares)
	adds = set(shares) - set(es)
	for r in rms:
	self.api.api_delete(f"/shared/{r}")
	for a in adds:
	self.api.api_create(f"/shared/{a}")
