[feature] Vote Commit: Prevent similar file naming for JSON commit files

[hypnotortoise]

Feature

What is the feature?

Currently the naming method for fileName is unique, but has a disadvantage it the proposer has multiple proposals open and is using the same title naming sequence (>=20 chars) for the proposals. The unique part is then only made of the timestamp suffix (when the voter has committed his vote) which can be in different order than the initiated proposals creation date. This can lead to confusion for voters in the revealing phase of the proposals.

Examples:

• https://community.digix.global/#/proposals/0xe5ad839313a886a728e0d3c703124f2ead82f36418fdffb559f7a994e726d52e

How can it be done?

Two suggestions (* preferred):
*1) Include part of unique proposalId into fileName
2) Don't allow proposers to use the same title sequence in proposal range (0,20) as existing proposals.
