Add the string "to present" to ongoing contributor role dates that display on user profiles and organization profiles

Problem/Motivation

When a user adds a contributor role to their profile, they have the option to leave the role end date field blank if they are still currently in the role. The role displays using the YYYY-MM format on their user profile, and if they also populated the Organization support field for that role, on the organization's profile page.

With some dates in particular, this can be confusing to users because the date range appears to be a year range that has ended, instead of an ongoing role. For example, If I were in a role starting December 2006 and am still in that role presently, it will display on my profile and organization's profile as

2006-12

which could be misunderstood to mean that I was in that role from 2006 through 2012, instead of December 2006 and ongoing.

Steps to reproduce

Add a role start date to a contributor role without a role end date and save.

Proposed resolution

For ongoing roles, add the string "to present" after the role start date
