Lowercase lemmatization in pipe, when tok2vec disabled

## Introduction
Hi! I am using spaCy lemmatizer for some tasks. I saw that when using a pipe to process the data faster, I'm getting different results with tok2vec disabled or enabled. Maintaining case-sensitivity is critical for me. Is the below behavior expected?

## How to reproduce the behaviour
### Case1
```python
import spacy
nlp = spacy.load("en_core_web_sm")

for doc in nlp.pipe(["Hello! My name is Marcin.", "I have a SFTP server running in my HomeLab"], batch_size=100, n_process=1, disable=["ner", "tok2vec"]):
for token in doc:
print(str(token), token.lemma_)
print("")
```
Output:
```
Hello hello
! !
My my
name name
is is
Marcin marcin
. .

I i
have have
a a
SFTP sftp
server server
running running
in in
my my
HomeLab homelab
```

### Case2
```python
import spacy
nlp = spacy.load("en_core_web_sm")

for doc in nlp.pipe(["Hello! My name is Marcin.", "I have a SFTP server running in my HomeLab"], batch_size=100, n_process=1, disable=["ner"]):
for token in doc:
print(str(token), token.lemma_)
print("")
```
Output:
```
Hello hello
! !
My my
name name
is be
Marcin Marcin
. .

I I
have have
a a
SFTP sftp
server server
running run
in in
my my
HomeLab HomeLab
```
