Tact produces invalid FunC code for modifying load function

[Gusarich]

This line:

let x: Int = beginCell().storeUint(0, 1).endCell().beginParse().loadUint(1);

Produces this FunC code:

int $x = begin_parse(end_cell(store_uint(begin_cell(), 0, 1)))~load_uint(1);

Which results error:

error: lvalue expected before `~load_uint`
