[FIX] project: parse the context given by the backend

Before this commit, the context retrieves when the user clicks on a
Profitability section is not parse, and since this context is a string
containing the JS object with the context added, the context is not
correctly added with the existing context.

This commit parses the added context to correctly append it with the
initial one.
