bug#23298: 25.0.92; electric-pair-delete-pair doesn't check if parens are balanced |

When pressing Backspace key, with electric-pair-mode enabled,
it unconditionally deletes the following char, if its the matching pair.
Ideally, it may better check if it breaks the equilibrium of
braces/quotes.
Eg: code: (char-before (point))
|_ point location
If my point (cursor) is just before the last paren (the cursor is
blinking on the last paren), and I press backspace until the beginning
of "point"[0], and then one char back[1], it just deletes the bracket,
without checking if the parens are balanced.
code:
[0] (char-before ()
|_point location
[1] (char-before
|_ point location
This could be the case of quotes, braces, etc.
