Completion adds superfluous "=" to field name

[chbndrhnns]

Describe the bug
The plugin produces a SyntaxError when completing field names.

import pydantic

class M(pydantic.BaseModel):
    old_password: str ="abc"
    new_password: str = "abc"

def test_():
    assert M(oldnew_password="def")

To Reproduce

1. Put cursor after old in the last line
2. Ctrl+space
3. Tab complete
4. Gives me assert M(old_password=="def")

Expected behavior

Not comparison, but assignment:

assert M(old_password="def")
