Updating an existing deployment using appName fails

[toph-allen]

Updating an existing deployment without an rsconnect subdir present fails when selecting the content to update using appName. (Updating using appId seems to work.)

The logs (attached) make it seem like maybe rsconnect is calling Connect's API expecting to get a single result, but is getting multiple results, and is thus passing a vector of URLs to curl instead of a single URL.

The presence of multiple seemingly-identical results might be a Connect bug, or it might be incorrect API usage. (Perhaps the endpoint is returning all matching bundles, rather than all matching content items.)

3: Abort this deployment and supply a custom `appName`.

This is happening because the result from rsconnect::applications() contains repeated entries. We do not appear to be paginating through the result set.

I verified this fix, marking this issue as done.
