Setting attack speed base to a low number gives some items a negative attack speed

Setting attack speed base to a low number gives some items a negative attack speed, effectively disabling the ability to properly attack with it.

What I expected to happen was...:
After setting a player's base attack speed attribute to 1, I thought items such as axes should keep their innate attack speed, or have it modified to a number above 0.

What actually happened was...:
Items such as axes have a negative attack speed, disabling the ability to attack with full damage.

Steps to Reproduce:
1. Enter /attribute @p minecraft:generic.attack_speed base set 1
2. Most tools and weapons will have a negative attack speed.
