…es - EXO-71462 - Meeds-io/meeds#2572. (#4172)

Before this change, when create a user and add him in
/platform/externals group and remove it from /platform/users group then
remove the user from /platform/externals and I put it in /platform/users
and go to people page/ spacex member app where the user is member, the
user is marked as external on his card. To resolve this problem, change
the display condition of this component from boolean to String. After
this change, The user is marked as external on his hard for people page
and space members.
