Move v3 member API calls to v5

[jmgasper]

REF: https://topcoder.atlassian.net/browse/PROD-4215

We need to move the v3 member ID calls over to v5.

The calls that I see are:

• On login, we get the profile information for the logged in user via v3
• When assigning a member to a task, we use the v3 member ID to auto-complete when typing

We can copy these updates into the develop branch:

• https://github.com/topcoder-platform/work-manager/pull/1504/commits/8cc4425d2030e1131f646dd00b2330c3e48e6f98
• https://github.com/topcoder-platform/work-manager/pull/1504/commits/cef9641a25486f266062acc3a454f92a0b36e170

But we also need to handle the searchProfilesByUserIds call and update that to the v5 API:
