bug: a single erroneous process crashes fetching an election list

[elboletaire]

Describe the bug

An organization containing an erroneous process cannot retrieve its election list, getting an Invariant failed error.

In some scenarios this error shows as Invariant failed: Census identifier is missing or invalid.

To Reproduce

Under the dev environment you can check this org: 0x4c0365ffe55e3239273af8508265aed2d3d0a906 which has been created reproducing the issue.

Anyway, here's the full process to recreate the issue:

• Having an organization created
• Have some valid elections (so you can check it does not return anything later)
• Manually create an election without a census
• Try to fetch the organization elections, in the catch method you'll get the invariant failed error.

Current behavior

No elections are retrieved at all and an error is thrown

Expected behavior

To get the list with all elections, even erroneous ones (these should probably come with the missing or erroneous fields).
