Use destructuring-assignment instead of delete operator

Operands for delete must be optional on TypeScript 4.0.

When using the delete operator in strictNullChecks, the operand must now
be any, unknown, never, or be optional (in that it contains undefined in
the type). Otherwise, use of the delete operator is an error.
