execute store sometimes does nothing

Some specific commands of `execute store result/success ..` do nothing.

It is common to emulate an and-gate like this: `execute store result score result foo if score cond_a foo matches 1 if score cond_b foo matches 1`.

What I expected to happen was...:
I expect that the variable `cond_a foo` is set to 1 if `cond_a` and `cond_b` both match 1. Otherwise the variable `cond_a foo` should be set to 0.

What actually happened was...:
If `cond_a` does not match 1 (aka the first subcommand fails) the value `result` does not get updated at all. This is problematic, because the `result` could be initialized to some arbitrary value other than 0 which will lead to invalid logic.

Steps to Reproduce:

1. create a scoreboard object, for example `scoreboard objectives add foo dummy`

2. set the value `return` of the scoreboard to 1, and the value `zero` to 0: `scoreboard players set result foo 1` and `scoreboard players set zero foo 0`

3. check if the score `zero` matches 1 and if the score `zero` matches 1 (the second condition can be anything but the first check must fail): `execute store result score result foo if score zero foo matches 1 if score zero foo matches 1`

4. Notice that the score `result` still has the value 1, even though it should be zero
