Remove deprecated (UNSAVE_) methods in ContactMap component

[Simply007]

Motivation

As a followup for issue #97, there is one component left with lifecycle method with prefix UNSAVE. In the react v17, it is required to remove those methods, because they are about to be deleted.

Proposed solution

Use different lifecycle methods as a substitution for the deprecated ones.

• https://reactjs.org/blog/2018/03/29/react-v-16-3.html

There are 2 occurrences of UNSAFE_componentWillUpdate and one of UNSAFE_componentWillReceiveProps.

Additional context

Current features on Contacts page:
If a user clicks on the address on Contacts (/contacts) page, the page is scrolled to the map and the address is focused on the map. Event when switching the languages.
