"Providers" in project.config only allows for a single entry

[dubaruzal]

This is using IntraMaps Roam 2.7.1.

If multiple providers are configured in project.config, e.g., for providing synchronisation options in Roam, it has been noticed that saving a project in ConfigManager wipes out all providers except for the "Inspection" one.

For example, project.config is configured with the following.

`forms:

• Photo_Capture plugins:
• search_plugin project_save_version: 78 project_version: 1 providers: Inspection: cmd: Sync.bat type: replication variables: SQLITE: db_replication.sqlite Lookup: cmd: Sync_Lookup.bat type: replication variables: SQLITE: db_lookup.sqlite search:`

After making changes in ConfigManager and saving the project, the "Lookup" provider disappears and only the "Inspection" provider remains.

Ordering makes no difference - whether "Lookup" is first or second, it still is removed when ConfigManager is saved.
