If a wife has executed a will prior to July 1, 1973, which remains unrevoked or unamended and in which she has not exercised a power of testamentary disposition over her one-half interest in the community property by specific reference thereto and affirmative disposition thereof, her interest in the community property goes to her surviving husband. The wife's will shall be valid in disposing of any other property over which she has testamentary disposition notwithstanding her legal disability under prior law to exercise a power of testamentary disposition of her interest in the community property.
