equal(=) added in project filter option

In admin's instance table, the filter with
'project' option filtering by exact matching
not by partial match.

the equal(=) symbol is missing at the end of the option.
there should be the = symbol to tell the user
it is doing exact match like other options.

in this patch the = symbol is added at the end of
the project option.
